Questions for Discussion: Balloon Brain: Designing a Helmet
Bubble wrap and egg cartons are two of the materials used to solve the problem of protecting the water balloons. Describe the properties of each material that make it a good choice. Are there any downsides to using either one? What other materials would you use? Why? Did you notice how the water balloons came to a complete stop very suddenly when they hit the wall and then the floor? How did the homemade helmets protect the balloons at the moment of impact? Take a look at some bike helmets. In addition to the materials that make up a bike helmet, what other criteria do you think designers take into consideration?
